A: Asymmetry

A is for asymmetrical shape. Look for moles with irregular shapes such as 2 very different looking halves.

B: Borders

Look to see if the mole or lesion has an irregular border. These could be borders that are irregular, notched, or scalloped.

C: Color

Look for changes in color. Look for moles or lesions that have many colors or an uneven distribution of color.

D: Diameter

Look for new growth in a mole larger than ¼ inch (about 6 millimeters).

E: Evolving

i.e. changing over time. This is the most important symptom of all. Suspicious symptoms in a mole may include: itching, oozing, bleeding, or a sore that does not heal. Rarely is pain involved.
